A3144E-JSM from JSMSEMI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSUP | power_in | Supply pin, rated for an operating supply voltage of 3.8 V to 40 V, with an absolute maximum supply voltage rating of -60 V to 60 V. |
| 2 | GND | power_in | Ground pin. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor, with absolute maximum sink current of 40 mA and output voltage of -0.5 V to 60 V. |
